 dichotomous, the upper ones sometimes exceeding the leaves. Flowers very

The timber of this tree is said to be hard, and valuable for building. The flowers in the 

 Japanese species are much smaller and more numerous, but the structure is the same, its 

 carpels having a wing of 2 to 8 in.

Flowers unisexual. Calyx 5-toothed or 5-cleft, Petals none. Staminal 

 column slender, bearinsr on the outside below the summit a rin^i: of 5 anthers 

 ^'itu parallel cells. Carpels of the ovary 5, nearly distinct, 1 -ovulate 3 style

The genus consists of two tropical Asiatic seacoast trees, of which tlie one extending to 

 Australia has the widest range. 



^ 1. H. littoralis. Ait. ; DC. Prod. I. 484. A tree, attaining a con- 

 sideral^le size. Leaves very shortly petiolate, oval or oblong, the larger ones 

 fully 8 in. by 4, but often much smaller, quite entire, coriaceous, glabrous 

 above, silvery underneath with a close scaly tomentura. Flowers small, nu- 



C'i'ous, in loose tomentose panicles in the Tipper axils much shorter than the 

 leaves. Calyx about 2 lines long. Staminal column in the males, pistil in 

 the females, much shorter than the calyx. Fruit carpels sessile, ovoid, 2 to 3 

 m. Ipng^ thick and almost woody, with a slightly projecting inner edge, and 

 a strong, projecting, almost winged keel along the outer edge.

Calyx tubular, 5-cleft at the top, often oblique. Petals 5, equal or the 2 upper 

 ones broader, the claws elongated, and all or two of them often with a lateral 

 appendage. Stuuiiual column adnate to the gynOphore, tmncate at the 

 top, or more frequently bearing 5 teeth or small lobes (staminodia), with 1 or 

 2 stipitate anthers between each, anther-cells divaricate, often confluent into 

 one. Ovavj nearly sessile on the top of the staminal column, 5-lobed, 5-celled,
